I regret that I didn’t get a before image, but this is the final installed product. It’s basically just a sheet of 3/4″ MDF with a dog door made out of cut carpet, and a plexiglass window. The window is held in place by some leftover coping strips. It would be nice to find a carpenter that would be willing to build us a custom dog/screen door that’s 8′ tall, but for now we’ll make due with my amateur efforts.
